Have a look at the graveyard of firms that tried being Intel Foundry customers over the past 15 years. Achronix was the perfect early foundry customer for Intel: FPGAs have regular physical structures replicated over the entire die. Yet they abandoned Intel as their early fab partner. Then Intel bought Altera and fucked it up as well.
Intel is on par with Google for killing non-core products. Look at StrongARM, various network processors, ultrawideband, ia64, their cellular modems... Anything that isn't going to directly help sell an x86 server, desktop or laptop CPU can be chopped, or at least not given the support needed to flourish. This was fine for decades, and Intel made a tonne of money doing that because that's what happens with monopolies: they print money. However, that strategy fell apart once the cost of fabs and fab R&D became high enough that more products across different market segments (read as: non-core market segments that Intel middle management doesn't care about) are required to generate a fair return on investment. Just look at how many top tier customers TSMC is able to amortize its fab R&D over today compared to Intel.
Any significant culture change at Intel is going to be nearly impossible given the inertia of 124,000 employees doing what they've always done.
